Toall whom, may concern: e Be "itknownthat we,BLAKE, and 1"`B"LA1`E, of Hartland, in the'county of VVind-, sor "and State of Vermo`nt,`have invented a new and Improved Machine for Sawing and 1" "BevelingGrooves or Slotslin Clothes-Pins; and we do hereby declare that the following isafull, clear, andeXact description of the saine, reference being had tothe annexed `i drawings,makin`g a part `of this` specification, in which,

` "Figurefl is aside view of our improved machine, the side of theframeneareSt the i eye being removed. 'Fig.` 2 isa front view of the same, the frontpart of the frame being removed. fFig. 3 is a plan or vtop `view ofthe same. i Fig".` l` is `a detached view of. the cutters, which cutI the b`evels,"at the lower. end ofdthe.` grooves `or` slots in the clothes-pins. i i i .i i Similar letters of reference indicate corr responding` partsinthe several figures.

` natureofourj invention consists, 1st, inthe employment or use `of a'ho-lding cylin`` ,i der, and"circular saw, arranged and operatf ing conjointly, as `will be `hereafter shown,

:e slots in the clothes-pins. l 3i ,v Our invention. consistsin the peculiar device orimeans employed `for holding the `clothes-pins in the cylinder, as will be hereafterfully` shown and described.

Bd. Our invention consists in the combina` ti-onf.` of the holding cylinder, circular saw, and bevel cutters, arranged and operating as e will be hereafter shown andfdescribed, whereby the clothespins are grooved or slotted and the lower edge of the groovesor 1 Slots, beveled at one operation.

To enable others skilled in the artto make f and use ourinvention, we will proceed to describe its construction and operation.

A,1Figs. 1, 2 and, represents a rectangular frame, constructed in any proper manner, to support the working parts of the "machine" TB, isa circular Vsaw hung on one end of `ashaft, said shaftrunningpin suitable r bearingson the upper part of the frame, A.

slotscut in it; one edge of` each slot, being beveled and brought to acutting edge, so as to form side cutters, (a) the edges of the" `slots being beveled alternatelyin reverse directions, so as to form cutters at each side of the saw,` see Figs. 12 and 3. i

i "for the purpose offorming the `grooves or The saw, B, hasa suitable` number of radial cLoTrrEs-PIN MACHINE.

D, representsV a cylinderor wheel, which Ainay be constructed of metal, and `provided 'with radial sockets" (b) in which wooden holders, E, are secured by screws, (c)` see Fig. 1. The front surfaces of these holders are grooved, or made concave,` as clearly shown at (al), Figs. 2 and 3. On the periphery of the cylinder, or wheel, D, and be-` tween the radial sockets (b) there are secured clamps, F. The clamps are secured to the cylinder, D, in this way-The periph-y ery of thecylinder is provided with pro- `jections (e) which lit in slots in the clamps, and pins (g) pass through the" Iclamps and pro3ections, shown clearly Fig. 3,`the clamps being allowed to move or turn on the pins, (g). .p i

The cylinder or wheel, D, is hung upon 'a shaft, G, which runsin `suitable bearings (It) onthe upper part of the frame, A. The` outerends of the bearings (71g) havescrew centers (i, i) which bear or fit into the ends of the shaft, G, for the purpose of allowing `the cylinder or wheel, D, to be shifted or `moved laterally, so that it kept in line with the saw.

H, is a disk or plate provided with a liange or rim (j). This disk or plate is permanently secured to the frame, A, and by the side of the cylinder or wheel, D. The disk or plate, H, is not perfectlycircular, as nearly one-half of itis somewhat smaller- Qi'nl diameter, than theother half, see Fig. 1, representing the smaller,I and the largerportion of the disk orplate.v `On the inner side of the disk orfplate, H,there is secured a rim or ledge (m) shown by dotted lines in Figs. l, 2 and 3, through albreak inthe flange (j). This rim or ledge corresponds in form to the periphery of the disk orplate H, one portion of it being larger thanlthe other.

Through the outer ends of the clamps `F, screws (n) pass; `the inner ends of which rest upon the outer surface of the rim or ledge (m) as shown in Figs. 1 and 2; the outer ends of the screws, bearing against the inner surface of theliange or rim (j) which projects ,at a right angle from the disk or late.

p The wooden holders, E, have slots (p) out in them, see Figs. 2 and 3, in order to allow the saw, B, to pass through;

On the lower part of the frame, A, there is a shaft, I, having at one end a hub or boss, J, to which. cutters, K, K, are attached.

may always `be e These cutters are placed tangentially witl the hub or boss, J, and are somewhat curved, as shown in F ig. 4.

The three shafts, Gr, I, C, are parallel with each other, and they are placed at such distances apart, that the slots (p) in the wooden holders, E, will as the cylinder, D, rotates, pass over the saw, the saw reaching nearly to the inner or lower ends ofv said slots; the cutters K, K, passing a certain distance into the slots (p).

The cylinder, D, is rotated by means of a belt passing over a driving pulley, L, on the shaft G; and the shafts, l, C, are rotated by belts passing over pulleys M, M, on said shafts.

The cylinder or wheel is rotated with rather a slow motion, compared with the saw, B, and cutters, K, K. The clothes-pins designated by, N, and shown in red in Figs. l, 2, and 3, are placed by hand in the wooden holders, E, as the cylinders or wheel rotates, and during the time, the inner ends of the screws (n) of the clamps F, are upon the smaller portion of the rim or ledge (m). Now when the inner ends of the screws (n) pass upon the larger portion of the rim or ledge (m) the inner ends of the clamps E, bind upon the clothes-pins, N, and secure them firmly in the holders, E; and the clothes-pins thus firmly secured in the holders are forced over or against the saw, B, which cuts a slot or groove in them of the requisite length, the side cutters, (a) smoothing the sides of the groove or slot; the clothespins then passing downward and the cutters, K, K, beveling the lower edges of the groove or slot, cut by the saw, as clearly shown in Fig. 4. .J ust after the clothes-pins have passed the cutters, K, K, the inner ends of the screws, (n) pass on the smaller portion of the rim or ledge (m) and the inner ends of the clamps, F, are relieved from the pins, N, which then tall from the holders, E, by their own gravity.

By the above invention the clothes-pins live do not claim the holding cylinder, D,

irrespective of its construction and arrangement, and the manner in which it operates in connection with the saw, B, as herein shown, neither do we claim the saw, B, separately, nor the cutters, K, K, for they have been used for analagous purposes; but

What we do claim as new and desire to secure by Letters Patent is,

l. The employment, or use of the holding cylinder, D, and circular saw, B, when both are hung on permanent shafts and operating as herein shown, so that the cylinder rotates with a comparatively slow motion, compared with the saw, and conveys by a continuous rotary motion, the clothes-pins over or against the saw for the purpose of forming the grooves or slots therein.

2. "We claim securing the clothes-pins in the holders, E, of the cylinder, D, by means of the clamps, F, secured to the periphery of the cylinder, D, as herein shown, and

operated by the rim or ledge (m) and flange,

(j) as herein shown, so that the clothes-pins will be firmly clutched in the holders, E, while being operated upon by the saw, B, and cutters, K, K, and allowed to fall therefrom when the grooves or slots are finished.

8. We claim the combination of the cylinder, D, saw, B, and cutters, K, K, constructed, arranged, and operating, as herein shown and described.
